machines and the like; aml the object is to pro-- duce a table of this character which is exceedingly simple and cheap, but nevertheless thoroughly etlieient.

The invention is illustrated in the accomainyingdrawingsz aml it consists in the coilstruetion and mimbinatiou of parts hereinafter described. and definitely set forth in the claim.

In the drawings, Figure l is a plan view of a sewing-maehine cabinet embodying my in vention. Fig. 2 is a transverse sectional view on the line 2 2 of Fig. I when the parts are in the position and condition shown in Fig. I. Fig. 3 is a similar view when the droplcuf is lowered alul the hole in the table-top covered by the extension-hip. Fig. 4. is an enlarged front view of the bracket-plate earrying the sheave and roller over which the, operating cable or cord passes, and Fig. 5 is a bottom plan view of the same.

The cabinet A consists of a top 0, having through it a hole a large enough to allow the machine-head to pass, and such sides 0' u' 'and end pieces u u as may be desired. The tabletop is really the only part of the so-callcd cabinet which is essential to the primary iiivention herein set forth, and this cabinet in whatever form it may be constructed may be secured to suitable Y su iporting-legs or frame members of the usua or any suitable conatruction. It has not been thought necessary, however, to show such legs or frame members in the drawings.

B represents a drop-leaf on which the machine-head niustbe firmly secured .by'auy suit-,

ablemeana.v 'lhis leaf is pivoted near its front edge to the cabinet, preferably to the 1 top a.

the position shown in Fig.1, where it fills the ma, have its middle part out out, as shown, I therein.

'Ihis drop-leaf is capable of taking so as to permit certain parts of the sewingiuachiue head to pass down through it. Secured to this drop-leaf is an omrating-urm I), the front end of which is bent upward and attached to the front part of the drop-leaf. The body part of this o airating-urm is therefore such a distance below the under side of the drop-leaf that it will not interfere with said sewing-niaehine mechanism. which passes through said drop-leaf. 'l his o mratiug-arm is ndjnstuhly secured to the rear side of the drop-leaf by iueans ot' a threaded stud I), socured lo said drop-leaf and passing through a hole in the mmratiug-arut. and two nuts 1' upon said stud. 'lhis operating-arm, it will be seen, serves as the means for connecting the cable II with thedrop-leaf. If onemibleulouc were used in aconstruction in which thisurm I) were not present, that cable would have to be attached wholly to one clul of the dropleat', and thus the pull tending to close and hold the drop-leaf closed would be applied wholly to thisend and would not probably be ellieient. Then. again, it is necessary when thedrop-leaf is closed that it shall nicely lit the opening in the table-top and shall beheld in the plane thereof. Without this adjustable arm this result would only be secured by making the cable ll of exactly the necessary length: but with this arm made adjustable, as shown, the cable may be made of approximately proper length, and the arm I) may be adjusted in its position relative to the dropleaf, so that the cable shall be effective in producing the result stated. The arm I) has sullicient flexibility, and' it is attached at its end to the drop-leaf with such a degree of Iooseness that it is possible that it may be moved relative to the drop-leaf quite as much as is necessary for securing the stated result. It is the position of its front end to which the cable is attached relative to the drop-leaf that is essential, and this is determined by the position of the nuts on the plate I), which passes through saidarm.

An extension-top is hinged to one side of thetop u on an axis at right angles to the axis of the drop-leaf, and this extension-top may be swung into the position shown in Figfl, where it serves as an extension of the top 1!, or into the position shown in Fig. 3, where it rests upon the top 1/ and closes the below A cable or cord II, preferably a small wire cable, is fastened at one end to the rear adjustable end of the arm I and at the other end to the extension-top 3 some lit tle distance beyond its hinge. This cable passes from this latter point of attachment overa grooved sheave 1 mounted in a bracketplatet'l, which is secured to the cabinet near the rear edge of the hole a, so that the axis of this sheave is at right angles to the axis of the drop-leaf. 'lhen theeable passes undera roller 1, also mounted in the same bracket-plate on an axis at right angles to the axis of the sheave. The cable then passes and is secured to the arm I), as before stated. When the extension top shown in Fig. I, it acts,through said cable, to lift the drop-leaf into the position shown in Fig. 2, where it is firmly held, because the cable ll, which lies in a groove in the top a and the extension 0, misses below'the axis on which the said extension-top swings. and therefore any weight upon thedrop-Ieaf when the same is raised cannot possibly cause it to more downward.

As showmthe drop-leaf has an extensionstri if: hinged to its rear edge on an axis paralle with its hinge-axis. Secured to one of the end pieces a is an inclined guide-strip l\', against which when the drop-leaf is being raised or lowered the rear edge of this extension-strip bwill engage and bethereby prerented from swinging by gravity into alinement with thcdrop-lcuf. When, however, the

rep-leaf is in the horizontal position, as 2, this extension-stripand the the drop-leaf as well engage shown in Fig. rear edge of is swung to the position.

signature in the presence stud secured to the The eombilmtion of a table-top having a.

hole through it, a drop-leaf, having a hole through it, hinged to the table-top and adapted to close the hole therein, a bent operatingarm having at its front end an upwardly-extended foot which is secured to the under side of the frontpart of said drop-leaf, a tl-n'eaded rear part of said dropleaf and passing through said ()lltEl'lttllIfl-ttllll, and two nuts on said stud, with an extensiontop, hinged to said table-top at right angles to the axis of the drop-leaf, a cable or cord secured at its ends to said extension-top and to said operating-arm respectively, and asheave, and roller, mounted at right angles to each other, with which said cable or cord engages, substantially as specilied.

In testimolrv whereof I hereunto allix my of two witnesses.
